Simulating Australian Urban Climate in a Mesoscale Atmospheric Numerical Model

摘要: We develop an urban canopy scheme coupled to a mesoscale atmospheric numerical model and evaluate the simulated climate of Australian city. The is based on Town Energy Budget approach, but modified efficiently represent predominately suburban component cities in regional simulations. conservation improved by adding simple air-conditioning prevent parametrization acting as energy sink during summer. In-canyon vegetation for areas represented big-leaf model, with largely reduced set prognostic variables compared previous approaches. Although we have used recirculation/venting in-canyon turbulent heat fluxes that employs two canyon wall budgets, avoid using fixed orientation averaging after integrating over 180° possible orientations. evaluated simulating Melbourne, Australia coupling it Air Pollution Model. combined system was found predict realistic climatology air temperatures winds when observations from Environmental Protection Authority monitoring stations. also produced plausible partitioning budget flux-tower studies. Overall, appears reasonable potential studying present predicting changes future climates
